This invention relates to an advertising machine wherein a plurality of advertisements are intermittently displayed by means of a power driven mechanism.

An object of myinvention is to provide a novel advertising machine in which a curtain is used upon which the various advertisements are placed and this curtain is intermittently stopped and moved through a novel gearing arrangement.

Another. object is to provide a novel meansof controlling the gear box through rollers bearing against the curtain, said rollers being actuated by projections on the curtain.

Other objects, advantages and features of invention may appear from the accompanying drawings, the-subjoined detailed descrip tion and the appended claims.

In the drawings:

' Figure 6 is a sectional view taken 6-6of Figure 3.

Referring more particularly to the drawings, the numeral 1 indicates the frame of my machine, and in this frame I journal an upper roller 2 and a lower roller 3. A curtain t-is rolled upon the rollers 23 and is intermittently moved so as to display the various advertisements by a means to be subsequently described. A gear box 5 is mounted upon a platform 6 in the frame 1. The gear box is actuated through an electric motor 7' which motor includes the armature shaftS, which shaft extends into the on line gear box 5. Within the gear box a worm gear 9 is secured to the shaft 8, and the gear meshes with aworm wheel 10 upon a trans verse shaft 11. A worm gear 12 on the shaft 11 meshes with a worm gear 13 on the cam shaft 14. The shaft 14 is constantly rotated as well as the cam plate 15 thereon.

A single cam 16 is providedon the plate 15 and the purpose of this cam .will. be further described. On the end ofthe shaft 11, opposite to the worm 12, I provide a bevelled gear 17 1 which meshes with a gear 18 on a shaft 19. The shaft 19 rotates constantly and a spur gear 20 is secured to-the shaft, and this. spur gear :meshes directly with a gear 21 on the clutch 22. An idler gear 23 meshes with the gear 20 and with a second clutch gear'24 on the second clutch 25. A. shaft 26 extends from the clutch 22 out of the gear box 5 and a sprocket 27 is secured to theouter end thereof. A second clutch shaft 28 extends from the clutch out of the gear box and a sprocket 29 is secured to the outer end thereof.

. A chain 30 encircles-the sprocket 27 and a sprocket 31 on the roller 2, and a second chain 32 encircles the sprocket29 and=a sprocket 33 on the roller 3. The shafts 2628 are alternately driven by the motor 7 by a means to be subsequently described.

driven, but are stopped at intervals and this arrangement will also be more fully described. The clutches 22 or 25 are actuated in the following mannerI Yokes 3435 slip over the shafts 26-28 respectively and one end of these yokes rests against a pin 36 or 37 The pins 3637 are set in blocks 38-39 respectively, which extend from the wallofthe gear box 5. The pins-are urged outwardly by coil springs 40-41 respective ly and one or the otherof these pins is held against inward movement by a sliding bar 1-2. This bar extends into the blocks 32 339 and is adapted to beslid over the Inner. ends of either of the-pins 36*37 as shown in Figure 5. When this bar is moved over the inner ends of the pin 36 or 37, this pin cannot retract and consequently any force supplied to the outer end of the yoke 3435 will press the clutch 2425 into engagement. All of which will be subsequently described in detail.

The bar 42 slides back and forth over the edge of a finger 43, which finger is actuated from an arm 44 on the outside of the gear box 5. This arrangement is shown in Figure 3 .of the-drawings. The arm'44 is swung upwardly or downwardly through the medium of links 4546 which extend. downwardly to a roller 47, bearing against the outside of the curtain 4 or through a link 48 which extends upwardly to .a roller 49 bearing against the curtain 4 at the top thereof. The rollers 4749 are tipped by means of a block on the curtain which passes over the roller to raise the same, and thus actuate the link 46 or 48, which in turn'raisesor lowers the arm 44 and thus it will the finger 43 to left or right to actuate one of the clutches 22 or 25. We will assume that the roller 49 is raisedtopush down on the link 48 andswings the arm 44. downwardly.

These movements will push the finger 43 to the-left as: shown in Figure 5 and will thus move the bar 42to the left.

.Goil springs '51 hold the bar 42 on either side ofthe finger 43' and stationary collars 52'53 are provided on the bar 42 so that said bar is yieldably moved to either side," that is if there is any obstruction for the bar 42 the finger '43 would not be bent or. otherwise injured since'thesprings 50 -51- would compressuntilthe obstructionwas re moved so that the bar could'travel into the position required. lVehave now moved the bar 42 to theleft' as shown in Figure 5, and we findth at the pin 36 can not be pushed inwardly. As previously. stated, one end of theyoke rests upon the pins 36-37 respectively. The other ends of these yokes are pressed; upon by a finger 54' which finger is journaled upon a pin 55 in the gear box 5; A plate 56is also pivotally mountedupon the pin 55 and this plate projects outwardly from the pin to adjacent the cam plate A rollerv 57 is journaled in the plate 56 and runs upon the plate 15. The

fingers 54-aie urged against the yokes througha spring 58 which springis set in a cup'59 ontlie plate 56. j A' bolt 60 extends into the cup 59 against thespring 58 for the purpose of: adjusting the tension thereof.; Asthe cam 16 comes-around against the roller 57 it will. raise the same, and in turn raise the outerend 'of the plate 56, thus tilting. the inner end of the; plate which includes-thecup 59 downwardly, which compressesthe spring 58 and will force the finger 54 against the yokes This-action quently when pressure is applied to the other end thereof by the finger 54, it will push the clutch member 61 inwardly, thus enga ing the clutch 22 which will drive the sha t 26 and the sprocket 27 to rotate the upper roller" 2. The other yoke is not operative to actuate the clutch 25 because the pin 37 can move inwardly when pressure is a-ppliedqthereto. The yoke-35 will tip uponthe end "of the clutch. 25 and thus depress the pin 37 and allow the clutch to remain stationary.

The plate 56 is held in this previously stated raised position by means of a latch 63." The latch 63 is in the form of a bell crank outof the gear box 5, and a rod 64 extends from the non-engaging side of the bell crank out'of the gear box 5. With the latch 63 engaged, the clutch 22 (or 25) will continue to be driven. The movement of the above named sprocket is stopped by'the following arrangement. A bell cranklever 65 is pivotallymounted on the outside. of the box 5 and one end thereof is secured to the rod 64; A link'66 extends downwardly to an arm 67 on the roller 68.'-. Theroller 68 is tripped by means ofa raised strip on the curtain4 and-when this strip passes under the roller 68,-:it will be pushed outwardly, which action will move the arm 66 upwardly to swing: the bell; crank 65and release the latch 63.

The: plate 56 'will now be tilted'opposite to the position shown in Figure'3, that isthe right-hand portion thereof -will"tilt' downwardly againstthe surface of the platet l5.

This action relieves the pressure on the yoke 34' and the clutch 22 will be disengaged. W'hen the'clutch'disengages, the shaft 26 and the sprocket 27 will necessarily stop. The clutch members 6162 are moved into disengaged position by a coil. spring 69' 69 which surrounds the shaft26 or 28. Obviously, when the finger 43 is moved in? the opposite direction from that previously described so that the bar 42 is moved to the right, then the pin 37 will beheld against retractionand the clutch 25 will'be engaged while the clutch 22 stands idle. A light switch 7 0 is secured to theoutsideof. the gear box 5-and a'st-rip7'1 is secured to theoperating lever 72 of" the switch. The strip is secured. to a pin- 73, which last named pin mounts the roller 57. When the roller 57 rides upwardly on the cam-l6, the arm-72 is pulled inwardly, whichoperatesthe switch and when the latch 63 is released, the

roller 57 drops down upon theplate 15 andthe switch70'is closed.

shaft 11 is constantly rotated, and this last named shaft thenv through the gears 1718 constantly rotates the shaft19 and the gear train 2l2324. This means that the one portion of both clutches 2225 are con stantly rotated. The other portion of these clutches is held out of engagement, and is actuated by means to be further described. The cam wheel 15 also rotates constantly through the shaft 11, and since the bar 42 must be moved to one side or the other, we will assume that it is in the position shown in Figure 5. In this position the pin 36 is held against retraction and when the cam wheel 15 rotates, the plate 56 is raised, the finger 54 is displaced and the yoke 34 will push the clutch 22 into engagement. This clutch then rotates the sprocket 27 and the upper roller 2 is actuated through the chain 30. The curtain 4 then moves upwardly upon the roller 2 until a raised portion on the curtain comes under the roller 68 when the latch 63 is released and the plate 56 will drop down upon the flat portion of the cam wheel 15. The clutch 22 is thus instantly released and the curtain remains stationary so that the advertisement thereon can be read.

As the cam 16 again comes around the plate 56 is raised and the same operation previously described is repeated. This continues until a raised portion on the curtain 4 comes under the roller 47, this roller is raised and actuates the arm 44 which swings the finger 43 and the bar 42 is then moved towards the right, as shown in Figure 5. The pin 37 'is now held against retraction and the clutch 25 is engaged in the same manner as the clutch 22 but the lower sprocket 29 is now rotated which drives the lower ro1ler3 and the curtain 4 rolls downwardly upon the lower roller.
